Abstract:
Objective:To observe the effect of chest pain center management model and emergency green channel on pre-hospital rescue rate of patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:Patients with STEMI admitted in Yunnan Provincial Emergency Center between January 2017 and June 2019 were selected as the study subjects. 522 patients with STEMI sent by emergency center were included in the observation group (chest pain center management model of first-aid), while 326 patients with STEMI who came to the hospital by themselves were included in the control group (emergency green channel for first-aid). The pre-hospital and nosocomial first-aid related indexes, cardiac function (assessed by Killip grade), rescue rate, hospital stay and incidence of complications were compared between the two groups.Results:The response time of visit, time of initial electrocardiogram (ECG) completion and total time of first-aid in observation group [(1.04±0.11)min, (1.56±0.25)min, (10.63±2.26)min] were significantly shorter than those in control group [(2.82±0.26)min, (5.99±1.06)min, (18.65±2.98)min, P<0.05]. The grade of cardiac function in observation group was significantly better than that in control group ( P<0.05). Compared with the control group, the observation group had higher successful rescue rate, shorter hospital stay , lower total incidence of complications [94.25% vs 42.02%, (6.09±1.02)d vs (8.92±1.65)d, 13.01% vs 32.12%, P<0.05]. Conclusions:Compared with emergency green channel, chest pain center management model can not only shorten first-aid related time of STEMI patients, but also improve their successful rescue rate, reduce incidence of complications and improve prognosis.
